Agreed with posts above, and just an addendum - by far the most time-consuming aspect of the new parts sellers job is the picking of orders you receive. It is worth every penny and every moment of time you spend in organizing that down to the nth degree, to save yourself countless hours of hassle and searching for parts once you get an order. Remember, once you get an order, you're on the clock to get that order out the door as quickly as you can - customer service matters not just for your own satisfaction at doing the job well, but for your feedback and your repeat customer ratio. Everything else you do - sorting, filing, uploading parts - is "off" that customer service clock. It doesn't matter how long any of that takes you (as far as your customers are concerned), so efficiency at the after-order end is the place to start and the most important to maintain. *Edited to clarify - pulling orders is by far the most time-consuming aspect of the new parts seller's job - a used parts seller has a huge time sink at the sorting end, too.
